### Various ###
knoppix noeject Do NOT eject CD after halt
knoppix noprompt Do NOT prompt to remove the CD
knoppix testcd|testdvd Check CD or DVD for defects
knoppix splash Use splash.ppm in initrd as boot pic
knoppix trace create an open() trace in /open.trace

Hint: Using the default DE-bootimage, SYSLINUX boots with german keyboard
layout. The '=' letter is located at Shift-0 on this keyboard (just in
case you want to change keyboard and language with lang=us).

*) Try "knoppix pci=irqmask=0x0e98" if (you have a notebook and) your
PS/2 mouse doesn't work. (Possibly caused by a BIOS-flaw on your board,
BIOS updates can help.)

If your KNOPPIX CD produces strange noises during boot, or you see
frequent errors like "cloop: read error", or programs on your KDE
desktop keep crashing randomly, then your CD image is probably defective
or incomplete, or your CD-burner created a defective CD due to wrong
writing speed or bad media. This is the most common error reported.
Please boot with "knoppix testcd" to check if the CD is OK.

In case of a failing hardware autodetection, try booting with any of
the "no-" options as shown in the table above, like in
knoppix noagp noaudio noapm noapic nolapic acpi=off pci=bios
pnpbios=off nodma nopcmcia noscsi nousb ...
to skip some critical parts of the autodetection system.

The "noswap" and/or "forensic" boot option is useful for a forensic
analysis without touching existing swap partitions.

Some Boards apparently don't pass the proper memory size to the
linux-kernel. It may cause the message "Panic: cannot mount root file
system" and the system hangs. Use "knoppix mem=512M" to solve that
problem if your system has 512MByte memory for example (caution:
you MUST use a capital "M" here).

---

If you need additional modules for starting controllers needed at boot
time, just copy the corresponding *.ko files from /lib/modules/* over to
/modules in the initial ramdisk (remaster needed).

If you place an update*.zip or update*tar.gz file on the medium holding
the KNOPPIX data, it will be unpacked onto the overlayed filesystem
before starting "init", thus allowing quick reconfiguration of the
system.

The file "knoppix.sh", if residing in the main KNOPPIX directory, will
be execuded after autoconfiguration and before starting the graphical
desktop. It can be used in order to start additional services.

If you wish to remaster the CD, please don't forget to specify
-no-emul-boot -boot-load-size 4 -boot-info-table \
-b boot/isolinux/isolinux.bin -c boot/isolinux/boot.cat
as option to mkisofs. Otherwise your CD or DVD won't be bootable. The
directory KNOPPIX, containig the compressed filesystem file "KNOPPIX",
must be located in the top level directory of the CD.

Caution: X-Screensaver: Don't start xlock or any screensaver that
requires a password. There are no default passwords on KNOPPIX,
i.e. all accounts are LOCKED unless you explicitly set a password.
See also README_Security.txt about this issue.
If you accidentially hit the screensaver button in KDE,
switch to one of the textconsoles by Control-Alt-F1 and kill
the screensaver (or just set a password for the knoppix user).

If you would like to edit your X-Server configuration manually
(config file /etc/X11/xorg.conf), use "knoppix 2" to boot
into runlevel 2 (textmode only) and, after changing the X
configuration, start the X environment with "init 5". Note that
you can always leave the graphical environment with "init 2", and
restart it later with "init 5".
